Why does my car hesitate when I give it gas?
A vehicle that hesitates while accelerating or while driving up a hill may have a weak fuel pump. Fuel injectors may become dirty over time and not be able to provide as much fuel to the cylinder as is needed. Dirty fuel injectors may cause the engine to run lean which will in turn, cause hesitation when accelerating.

Why did my car suddenly stop accelerating?
There are many reasons why your vehicle may be losing power, especially when accelerating.

Malfunction of actuators such as: Bad injectors, bad fuel pump, bad spark plugs.
What to do when your car engine hesitates?

Why does my car hesitate when going up an incline?
If the vehicle has an external fuel filter, it’s wise — and inexpensive — to replace it. Likewise, a failing fuel pump (also mounted in the tank) can cause fuel starvation, especially when the vehicle is heading up an incline. 8. O2 sensor
